...' ability to reach a female-mimicking LED within a Y -maze. We show that as the intensity of illumination increases, the proportion of males reaching the female-mimicking LED declines. Brighter illumination also increases the time taken by males to reach the female-mimicking LED. This is a consequence...

... ants to make multiple visits to sucrose on a runway which alternated between lemon or rosemary odour, and the presence or absence of trail pheromone, and then tested for preference between the odours on a Y -maze, in order to investigate the effect of pheromone presence on learning. Pheromone presence...

...; they readily explored in a novel environment but resident, worker mole-rats explored more slowly. In the Y -maze, animals entered the escape hole significantly faster by the second day; however, they did not make fewer wrong turns with successive days of the experiment. Female dispersers did not show any...

... be interpreted as a search strategy. A similar turning bias was shown for groups of ants in a symmetrical Y -maze where twice as many ants chose the left branch in the absence of optical cues. Wall-following behaviour was tested by inserting a coiled tube before the Y-fork. When ants traversed a left-coiled tube...

... is relatively rudimentary and based upon simple elemental-type visual processing. In the present study, we test the ability of honeybees to learn 4-bar asymmetric patterns in a Y-maze with aversive–appetitive differential conditioning. In Experiment 1, a group of bees were trained at a small visual angle of 50...

... to help solve novel difficult tasks, a process that involves top-down processing ( Miyashita and Hayashi, 2000 ). There is also evidence that prior experience with visual information can be used by the bee brain to solve novel tasks. If bees are trained in a Y-maze apparatus to discriminate between a disc...

...Ted W. Simon; Kevin Barnes ABSTRACT Haemopis marmorata , the green horse leech, is carnivorous and readily eats earthworms. Using a Y-maze with flowing water, we show that specimens of H. marmorata are attracted to live earthworms. Ablating the dorsal lip, the presumed site of the chemoreceptors...
